Abstract
Disclosed herein is a method of increasing the sugar (primarily glucose and fructose) content in grapes by applying to grape vines (primarily to the leaves) a compound which is vanillin or a carboxylic acid salt having from 3 to 5 carbon atoms. Grapes are customarily harvested when the sugar level is about 16% "Brix" and application of the compounds of the present invention gives the grower a better means of controlling sugar level so that the fruit can be harvested in an orderly manner.
